So there`s a threshold on how many people must play your game, read your book or watch your movie before it must be archived? I wonder what that number is.
Of course there's no specific threshold. And nothing must be archived.
If you asked a historian, then yes, EVERYTHING would have to be archived. If they had their way, you'd splice your genes and collect your shit.
If you asked a company like Ubisoft right now, then nothing is to be archived. The product is only supposed to exist as long as it can generate profit, and everything beyond that is optimally illegal, because otherwise, the argument goes, it could've turned up more profit, and by not doing that, it is the same as stealing money.
The point is that by the current letter of the law, nothing outside of original media is to be archived. And that's just not going to work out in the end. Software preservation is pointless without the appropriate means to run it. If it's even usable.
Ideally though, we'd archive everything in such a manner that it would be available, runnable, forever.
Pirates are still dicks, of course, but they're helping in the effort, albeit unwillingly. Pirates do not seed torrents to help historians, obviously. They want to show off their e-peen or something like that.
Again, if you look at these hosted illegal copies from the viewpoint of a historian though, then it's great that the games are readily available, playable, you can analyze them thoroughly and so forth, all that without having to rely on a perfect preservation effort from companies, who really aren't willing to help out there anyway. (Costs money, right? So no. That's the classic profit-oriented argument.)
We're lucky in that regard that there are so many console hardware enthusiasts out there. Specifically emulator writers are very important people in that sense. Without them, good luck in finding all the pristine SNESes you'd need for the different versions of games, for example.
If you're saying, "but why give a shit?", then you're just arguing against historians in general. You could do that, I however applaud their efforts. For example, I find reading about the crazy stuff the Romans did very entertaining. I find reading reviews of the Red Scare very insightful. This will of course expand to video game media of the 1970s-2010s eventually, we just don't really get it because we're still in the thick of it, and because we grew up with it and are so intimately familiar with the most intricate details. That'll pass though. I hope someone can connect the dots generations later and relive this crazy nerd nonsense, set it in relation to general social movements at our times, make smart remarks about all that, and if it's done because someone torrented Megadrive games like a madman, then so be it.
In a sense, this is something that goes parallel to the first archaeologists blatantly stealing from Egyptian graves, then hoarding the treasures in museums of oppressing countries. Sure, at the time, it was a horrible thing to do. Now, the treasure hasn't rotten away because of it.
Not ideal, yes. And piracy sucks. That's why I argue for a concerted effort by the game industry to consciously preserve everything in an open digital format, preferrably in a manner that doesn't make it trivial to distribute that collection for profit. But for that to happen, they'd have to organize somehow in the first place.
Too bad that these kinds of efforts require that an industry matures. Because the weirdest stuff is usually in the early, unorganized years.
Amusingly, DRM itself will be subject to historical review eventually. So we need to preserve that as well!
